1 May 2014 Reconstruction-free wavefront measurements with enhanced sensitivity
Author Affiliations +
We report the development of a new device able to record an optical wavefront with an improved sensitivity and without resorting to any reconstruction technique such as Zernike polynomial decomposition. A direct comparison with a standard Shack-Hartmann sensor is performed within the field of Z-scan-like experiments. It is also shown using computer-generated holograms that our device is suitable for characterizing phase discontinuities or sharp phase variations.
